I have a 98 ek (obd2a). I bought a full low comp b20 swap with a gsr trans out of a 99 ek (obd2b). He gave me the obd2b harness and an obd2b ls ecu. I bought a obd2a ls ecu to get the car running but its an auto. I know the car will run off of that ecu but it will also throw a cel because the ecu thinks the car is in park but youre moving. Is there any way to put a switch or to splice a wire so it doesnt think its in park? There must be a wire i could splice for the tcm to trick the ecu into thinking all is well. I want to get it set up to pass inspection now so at the end of the year i have no problems

 

It truly depends upon what's inspected, and what your legal authority considers passing by way of codes. Different states have differing emissions and signal requirements.

You may have to go through a failure and find out what's required or research your state/county/municipality laws.

 

Im in ny and even if i have an emissions code that comes on it can pass if i clear the code and drive it a certain amount of miles before the inspection. It will read as a pending code but not an actual code and therefore will pass

 

Again, you'll need to investigate what I stated above. But few are successful in what you're attempting.

 

I suggest you find a LS manual OBD-2A ECU... they are cheap on the used market because the demand is very low.

 

im going to have to but ill run the auto ecu for a wweek or two until im sure thats the only problem
